Аннотация:The activity of young stars possessing planetary systems (K2-231, EPIC 219388192, K2-136, Kepler-66 and Kepler-67) is investigated. We constructed maps of the temperature inhomogeneities on their surfaces and made conclusions on the evolution of changes in the positions of the active regions. The spottedness parameters S of the stars' surfaces were determined. The positions of the objects in the S-Age, S-P and S-Ro diagrams were studied. We conclude that they correspond to the general nature of the dependences established, earlier, for 1570 M dwarfs and, in this study, for 34030 stars.
